TECHNICAL FIELD
[0001] The utility model relates to the field of drill chuck, especially to a quick tightening wrench for drill chuck. BACKGROUND
[0002] When drilling, the drill bit needs to be installed on the drill chuck, and when not in use, the drill bit needs to be removed from the drill chuck. In the process of machining, the commonly used methods for tightening the drill chuck include using a key and knocking the drill chuck with an iron block.
[0003] When tightening the twist drill with the key, the twist drill cannot be firmly locked due to the short key rod, which cannot meet the cutting resistance of the twist drill. Meanwhile, the key tooth and the drill chuck tooth may shake, and the key tooth may be easily worn during the force process. Although the iron block can meet the tightness of the twist drill, it is difficult for beginners to grasp the point of the hammering force, which may cause injury. Meanwhile, the repeated use of the method may damage the drill chuck tooth under the knocking action. SUMMARY
[0004] The utility model discloses a quick tightening wrench for drill chuck, which solves the problems in the prior art.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a quick tightening wrench for drill chuck, comprising a sleeve, a rotating groove is formed in the outer wall of the sleeve, a bolt hole is formed in the inside of the sleeve, the bolt hole penetrates the rotating groove, a pawl is installed in the inside of the rotating groove, a through hole is formed in the inside of the pawl, a bolt is installed in the inside of the bolt hole, the bottom of the bolt penetrates the bolt hole and the through hole, a nut is threadedly connected to the bottom outer wall of the bolt, a first threaded hole is formed in the outer wall of the pawl, a first threaded column is threadedly connected in the first threaded hole, and a handle is fixedly connected to the other end of the first threaded column.
[0006] The position of the bolt hole corresponds to the position of the through hole, and the nut is located at the lower end of the sleeve.
[0007] A first anti-skid sleeve is sleeved on the outside of the handle, and a first circular ring is fixedly connected to the outer wall of the first anti-skid sleeve.
[0008] A second threaded hole is formed in the other end outer wall of the handle, a second threaded column is threadedly connected in the second threaded hole, and an extension handle is fixedly connected to the other end of the second threaded column.
[0009] A second anti-skid sleeve is sleeved on the outer wall of the extension handle, and a second circular ring is fixedly connected to the outer wall of the second anti-skid sleeve.
[0010] The inner wall of the sleeve is provided with a rubber ring, and the outer wall of the rubber ring is provided with a hollow groove.
[0011] The utility model has the advantages of the following:
[0012] 1. Compared with the prior art, the device is designed according to the lever principle and is composed of five main parts, namely a handle, a pawl, a bolt, a nut and a sleeve. When in use, the sleeve is sleeved on the periphery of the drill chuck of an electric drill. When the handle is pulled to loosen or tighten the drill chuck, the pawl rotates around the bolt as the center. In the rotating process, one branch of the two branches of the pawl is clamped in the groove formed on the outer wall of the drill chuck of the electric drill. When the handle is pulled, force is applied to the handle. The entire wrench rotates around the center of the drill chuck as the center, thereby driving the drill chuck to rotate, so that the work of loosening and tightening the drill chuck is realized. The tool is easy to operate, improves the safety factor, improves the production efficiency, avoids the wear of the key cone teeth and prevents the cone teeth on the outer wall of the drill chuck from being damaged or broken.
[0013] 2. Compared with the prior art, the device is connected with an extension handle at the other end of the handle. In the case of heavy load cutting, the length of the force arm is conveniently increased, and the torque is increased. The first anti-skid sleeve and the second anti-skid sleeve are respectively sleeved on the outer walls of the handle and the extension handle, so as to play the anti-skid role, avoid the cold feeling of holding the handle or the extension handle in winter and improve the comfort of use. The first circular ring and the second circular ring are respectively connected to the outer walls of the handle and the extension handle, so as to prevent the wrench from being pulled off the hand.
